Nick Mason and becan. 

I'm trying to decide between Heavy and Sphere for mainly rock recording...anyone have a preference between the two?

check out the 'black album drums', don't be fooled by the metallica/metal inference, they can do a lot off different styles. i own all the bfd xpansions that i know off and if i had to pick just 1 to keep it would be them.
 
heavy and sphere are quite good, you really can't go wrong either way
 
[edit] put the link up for black album drums, but as ussual the forum ate the post, why it hates fxpansion links is beyond me, but . . .

I really like the Vinny Appice kit made by Sonic Reality.

I just purchased Heavy and Sphere and like them both, but for what I'm working on I'm enjoying Oblivion just a bit more... 
 
I believe both of those have demo kits available, so you might want to give them a try.

I tend to write jazz oriented stuff when I think of acoustic drums, so I use Yamaha Maple Custom Absolute (it came out before Jazz Maple) and Virtually Erskine a ton. I also love both of the Zildjian Digital Vaults and Signature Snares 1. The Roy Haynes snare kills.

Yea, I'm kicking myself for not picking up Oblivion last month when it was on sale.  I'm fairly new to BFD3 but have realized in this short time how it stands out amongst the other drum VSTs I have laying around now.  I'm going to hold out for Oblivion and save my pennies for the Black Album Drums.  Grim, wish I'd given the demo tracks a listen...I can totally see now that it's much more than just the Metallica sound.  No GAS this time around...I'll wait for the expansions I want vs. the ones that are on sale.

OK I've finally got a kit that I'm totally digging!
 
1. Start with the Oblivion kit
2. Change kick to DW Kick (Processed) from BFD Sphere
3. Link a second kick as SDB Kick from Sonic Realities Epic Drums 60s downbeat
4. Change the snare to EJB Kit 6 Snare from Platinum Samples Joe Barresi Evil Drums
5. Have friend actually mix the damn thing. Includes parallel bus with UAD Fatso and run through UAD Pultec, UAD Ampax, and UAD Ocean Way
 
Man BFD is DEEP.
 
I've saved this as a preset so I can recall at will.
 
So cool to have a kit that sounds so good... :)
